【 摘 要 】

In an effort to develop a QA/QC protocol to be used in the development of new pads, we are employing a tabletop unilateral NMR relaxometer called the NMR MOUSE (MObile Universal Surface Explorer). Model materials of varying crosslink density first demonstrated the applicability of the method. Analysis of deformed pads returned from service has been shown to be clearly distinguishable by the NMR MOUSE. Finally, we have quantified the variables associated with taking the relevant measurements and believe that the NMR MOUSE is a viable production and surveillance tool for screening of future DC745 parts.
